Application lecl March 529, `19530. Serial No. 369,629.

`Janesville, in the county of Rock and State of Wisconsin, have linvented certain new and useful improvements in lleating Crlystems; and l do hereby declare that the following is a full, clear, and enact description thereof.

ll/ly invention relates to new and useful improvement in heating apparatuses, and pertains particularly to one pipe steam heat ing systems.

ln systems of this character it is frequently difficult to cause the water of condensation to return to the boiler owing to back pressure, the presence of steam in the return pipe line and other causes. My invention therefore has for its particular object to overcome these ditliculties and permit the ready return to the boiler of the water of condensa tion.

`With this general object in view, the invention resides in certain novel features of construction, combination and arrangement of parts which will be hereinafter' more particularly described and claimed and shown in the accompanying drawing, wherein the ligure represents portion of a steam heat ing system constructed in accordance with the invention.

Referring to this illustration, it will be seen that this improved steam heating system includes a steam generator or boiler l in which the water is adapted to be retained at the level w, a main steam supply pipe 2, one or more radiators 3 having a one way connection l with the supply pipe, a return pipe 5 and one or more condensation pipes 6 connecting the supply pipe and the return pipe. lt will be noticed that the return pipe 5 has its main portion substantially on the level of the water line 5c or slightly thereabove, although it enters the boiler l below the water line as at 7. ln such a system as this steam is designed to enter the radiator 8 to completely lill the same, steam being continu- .ously supplied by the boiler to take the place of that which condenses; the water of con densation from the radiators enters the sup-v ply pipe 2 and flows therefrom down the pipe 6 to the return pipe 5.

However, the system with which my invention is designed to be used, is provided with one or more radiators 8 located adjacent to the boiler l. between the normal level of the steam supply pipe 2 and relatively ad- `bottom of the radiators.

jacent the level of the return pipe 5, these radiators being supplied with steam by an auxiliary supply pipe 9 which extends vertically from the main sup` ly pipe 2 to the Vater of condensation from the radiators 8 flows therefrom through an auxiliary condensation pipe 10 which indirectly connects with the return pipe 5.

"if this pipe 10 is directly connected with the return `,pipe 5 there is a probability of steam entering the latter and setting up a back pressure which will prevent the water of -condensation returning to the boiler. llllherefore to eliminate any likelihood of the return being interrupted, l have provided a water seal or trap between the auxiliary condensation pipe lO and the return pipe 5. This arrangement preferablyl comprises a pipe line in the form of a vertically positioned substantially rectangular loop 11, one end of which is a continuation of the vertical auxiliary condensation pipe l0, while the other end enters the return pipe 5 as at 12. rlhe top or highest point 13 of the loop 1l is a considerable distance above the water line a', but the lowest portion la thereof is below the bottom of the. water in the boiler l.

rThus, due to the water of condensation, the loop 1l is completely filled with water, or the level of the same therein is above the water line However, even though the water in the loop is below the normal water line, any steam which tends to pass into the aux iliary condensation pipe 10 will be trapped and prevented from flowing into the return pipe 5. As a result of this construction the water of condensation readily flows from the return pipe into the boiler, and in fact, is aided in some instances by the pressure of the steam in the auxiliary condensation pipe i() pressing on the columns of water in the loop 11.

From the foregoing description taken in connection with the accompanying drawing it will be seen that l have devised a very simply constructed arrrangement for taking care of back pressures in one pipe steam heating systems, and especially in those in which certain of the radiators are relatively close to the normal water level and adjacent to the steam generator. Various changes may be made in the form and proportions and in the general association of parts without departing from the principles or sacrificing any of the advantages of the invention.

I claim: l 1. In aY steam heating system, a steam, generator, a steam supply pipe, a radiator oon- Vneoted'with the supply pipe relatively closev to the generator,

a return pipe connected with the base of the generator to return water of condensation thereto, a condensation pipe leading ator, and a neoted with downwardly from the radipipe loop having one end conthe Condensation pipe and the i other end with the return pipe, the top ofthe tor, a branch pipe leading from the main W steam supply pipe to said radiator, a

second branch supply pipe connected with the main steam pipe and leading to a lower story, radiators connected with the last named branch pipe, a condensation pipe leading downwardly from said lower story radiators, a return pipe connected with the base of the generator to return water of condensation thereto, and a pipe loop having one end connected with the condensation pipe and the other end with the return pipe, the to of the loop being a relatively considerable distance above the water level of the generator, but below the bottoni of the radiators in the lower story, the bottoni of the loop being below the lowest point of the return pipe.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee, and State iseonsin.
